- However, network connection not yet working. Comments appreciated.
- Baptiste Comment: To be honest, going through Windows is a big added complexity to the setup. I would recommend installing an Ubuntu/Debian dual-boot and running QEMU (+ libvirt) from there if network problems persist. CUDA/GPU support should be solid on Ubuntu.
- Paul - Dual boot is not currently an option as the only graphics card is the single Nvidia GPU (not paired with Intel embedded/Nvidia external) which causes lock-up. When nographics then Ubuntu still crashes complaining of ACPI issues. When ACPI turned off no storage is recognised. Therefore, qemu on Windows is the only option to emulate Aarch64 in this hardware (currently).
- Qemu start for an emulated Aarch64/Ubuntu environment
- Lab Updates - hardware changes at Colo Nov.11/12 2019. Currently no known facility to host water-cooled nodes.
- Tensorflow script has been documented - comments appreciated - Building TensorFlow on AArch64
- Problems with NumPy building. Bug appears in OpenHPC and RedHat. Perhaps consider fetching latest toolchain builds from Linaro Toolchain team.
- Futurewei hosting - How does affect 'EAR' restrictions for technology transfer if we login to a Futurewei hosted system?
- Compiler Updates - Open
- LLVM updates continuing for A64FX by Fujitsu under NDA.
- GCC updates for A64FX - there are currently no Fujitsu resources. Non-NDA resources cannot be used until the A64FX technical specification is made available.
- A64FX specification 'may' be released 1Q2020.
